The problema is:"problem of compilation of Arduino uno".thanks.
Have you looked at any of the many threads dealing with I2C LCD issues? One of the most recent is here --> http://forum.arduino.cc/index.php?topic=398735.0
For about 14000 more put your thread title LCD I2C into the search box at the upper right and stand back.
